Mammogram warns against cancer.
Often-conflicting results from studies on the value of method mammography have only fueled the argumentation about how often women should get a mammogram and at what age they should start. In a new study of previous research, experts have applied the same statistical yardstick to four large studies and re-examined the results. They found that the benefits are more predictable across the large studies than previously thought vigrx box. All the studies showed a profitable reduction in breast cancer deaths with mammography screening.
So "Women should be reassured that mammography is thoroughly effective," said study researcher Robert Smith, senior helmsman of cancer screening for the American Cancer Society. Smith is scheduled to present the findings this week at the 2013 San Antonio Breast Cancer Symposium sleeping. The findings also were published in the November offspring of the newspaper Breast Cancer Management.
In 2009, the US Preventive Services Task Force (USPSTF), an unallied group of national experts, updated its recommendation on mammography, advising women elderly 50 to 74 to get mammograms every two years, not annually.The group also advised women old 40 to 49 to talk to their doctors about benefits and harms, and decide on an one basis whether to start screening. Other organizations, including the American Cancer Society, take up to recommend annual screening mammograms beginning at age 40.
In assessing mammography's benefits and harms, researchers often looks at the number of women who must be screened to prevent one death from breast cancer - a copy that has ranged widely among studies. In assessing harms, experts occupied in into account the possibility of false positives. Other possible harms include finding a cancer that would not otherwise have been found on screening (and not been sensitive in a woman's lifetime) and anxiety associated with additional testing.
